Electricity and Universal Gravitational forces

Voltage is measured in __.

• volts.

• coulombs.

• watts.

• Amps

A 12 volt battery supplies voltage to two bulbs. How much voltage would each bulb get?

• 6 volts

• 12 volts

In a series circuit, the current is the same everywhere, it does not change

• True

• False

A 8 volt battery supplies voltage to 4 bulbs. How much voltage would each bulb get?

• 8 volts

• 2 volts

What is the voltage drop for each resistor?

• 9 V: all resistors have the same voltage in a parallel circuit

• Trick question! They all have different voltages!

• 9V: there is only one resistor in this circuit

• Trick question! They all have the same current!

What is the unit of Current?

• Volts

• Amps

• Watts

• Joules

What unit of measurement is used to measure electrical current?

• Ohms

• Voltage

• Amps

• Watts

Ohms are used to measure this

• Electric Resistance

• Electric Potential

• Electrical Current

• Light energy

What is the difference between a current and a circuit?

• A circuit is measured in volts while a current is measured in ohms

• A circuit is how much electricity is in a system while current is how many watts of electricity are in a circuit?

• A circuit contains electricity while a current contains water

• A circuit is the path electricity follows while current is the flow of electricity

A circuit has a current of 10 amps (I) with three resistors. If resistors A and B both have 5 ohms of resistance and the resistor C has 2 ohms of resistance, then how many volts are in the circuit? **Read me carefully**

• 120 v

• 10 v

• 100 v

• 70 v
